METHOD FOR PREPARING NANO-CARBON FIBER AND NANO-CARBON FIBER

摘要

The present invention is a carbon nano fiber, in particular the manufacture of a carbon nano-fiber having a twist of the carbon nano-coil, such as a carbon nano-twist or carbon nano-rope to provide a manufacturing method using a suitable catalyst, at least Cr, Mn, Fe, Co, Ni, or one selected from the group consisting of an oxide or a plurality of the material, the selected one or more of the materials from Cu, Al, Si, Ti, V, Nb, Mo, Hf, Ta, W, or the group consisting of oxides using a catalyst consisting of characterized in that for producing a carbon nanofiber by the catalytic CVD process as a raw material a carbon-containing gas.
